IMPROVEMENT IN ELASTIC SHA'FTlN-G.

The Schedule referred to in these Letters Patent and making part of the same' To all whom it muy concern: y

Be it` known that I, Ronnn'r Bnowx, ol" Detroit, in the county of Wayne and State ot' Miehigzi-lnhove invented :t new and uscf'ul I inprovmnent in Elastic Slntt'ting; und l'do hereby dechire that the following is n full, ele-nr, and exact description thereof', which will enuble others Skilled in the nrt to make und use the saune, relerence being had to the accompanying d 'nwing forming purt ol" this specification. l

Figure 1. is zr side View ot' my improred shuttingJ partly in section, to show the construction.

Figure 2 is n detail cross-section oi the suine, lnkcn through the line a; c', lig. il.

Figure 3 is :t detail sectional View ol' the saune, taken through the line y y, fig. 1.

Similnr let-ters ot` reference indicate corresponding parts.

The object ol` my invention is improvement inurrnngcments i'or preventing buck-lush in gearing, wherein thc wheels :unconnected with their shafts by menus of springs; und

The imnovenient consists in the construction und arrangement of parts, es hereinafter speeiiied.

A represents n shaft, und

B is n. bevel-gear wheel connected with it.

The gen1-wheel B securely bolted to the hollow cylinder O.

D nre two rings, pluced in und securely bolted tc the ends ofthe hollow cylinder- L", said rings having n circuler recess l'ormed upon their outer sides, ns shown in lig. 1, to receive the nuts ot' the bolts, by which the suid rings ure'securcd to the snid cylinder.

Through the centers ol'l the rings D nre formed eonienl holes, ythrough which the shaft A posses, snid holes tapering gradnollyirom the outer to the inner sides of snid rings, as shown in iig. 1.

'll urciconicnl bearings. which tit into the conical holes ol' the rings D, und which nre keyed tothe scid shaft A. Y

Upon the outer cylindrical-l parts of the bearings E nre placed rings F, which rest against the outer sides ot the rings l), und ure secured to thc beau-ings E by set-screws.

G ure thrc'c disks, connected to euch other upon the opposite sides oi" the shalt A, by partitions g', formed solid with said disks, thus forming :L chambercd or recessedcylinder, which is securely keyed to the shaft A.

1n the chambers or spuces between the disks G ue placed blocks of rubber Il', the ends of which rest squarely against the partitions y.

Between the other ends ot' the blocks tl und the other sides ot' the partitions g' are pla-ced segmental metnllicblocks I, which are screwed tothe hollow cylinder C, as shown in figs. l nud 2.

By this construction, when power or. resistance is applied to the shaft, the first eiectwill be to compress the rubber blocks H, thus relieving the teeth of the gearing from the sudden shocks.

Having thus described my invcntiolnl l claim as new and desire to secure by Letters Pntent- The combination, with the slnit't A nud gear-wheel B, of the hollow cylinder O, rings D D, secured to the cylinder by means ot screw-bolts, conical bearings E E, bzuuls F, with their clmnp-screws, inner chnmbcred cylinder G g', rubber blocks H H, and metallic blocks l', each of sn-id parts being constructed and ull relatirel y arranged as shown und described.
